1 Claim.

This invention relates to improvements in interchangeable settings forfinger rings, brooches, and other articles of jewelry, and the objectsof the invention are as follows:

First, to provide a finger ring which shall comprise a ring band havinga setting secured thereto, whereby bands of different size or ofdifferent ornamental character can be easily and quickly combined withsettings of different ornamental character to facilitate and makepossible to interchange a certain setting with various bands so that thequantity of settings which a jeweler has to keep in stock can bedecreased, thereby having a larger number of bands so as to be able tofit fingers of different sizes more easily.

Second, to afford facilities for the proper securing of the setting tothe ring band, brooch or the like so that the setting cannot be lostwhile the article of jewelry is worn.

Further objects of the present invention reside in any novel feature ofconstruction or operation or novel combination of parts present in theembodiment of the invention described and shown in the accompanyingdrawing whether within or without the scope of the appended claim andirrespective of other specific statements as to the scope of theinvention contained herein.

In the drawing:

Figure 1 is an enlarged side elevation of a ring constructed accordingto the invention, showing the ring band and the setting partially incrosssection on the line II of Fig. 3; Fig. 2 is a vertical section ofthe ring band and setting on the line 22 of Fig. 1; Fig. 3 is a top planview of the ring band as it appears after the removal of the setting;Fig. 4 is a bottom plan view of the setting as it appears after theremoval of the band; Fig. 5 is a cross-section of a ring constructedaccording to a modification of the present invention; and Fig. 6 is aside elevation of the modification shown in Fig. 5.

Similar numerals refer to similar parts throughout the several views.

The purpose of the present invention, as previously stated, is toconnect a setting to a band in such a manner that it can easily beinterchanged. This can be done in various ways, as for instance by asimple snap connection, by a screw connection, and the like. I prefer,however, to carry out this feature of my invention in the manners shownin the drawing and hereinafter described.

Referring first to Figs. 1 to 4 inclusive, the ring band I has a head 2with a flat surface 3, in the center of which is an internally threadedaperture 4; and the setting 5, which may hold a stone 6 or any otherornament, has at its bottom 1 a threaded pin 8 and notches 9 arrangedcircumferentially around the pin 8. The head 2 of the band I is providedwith a groove It, in which a resilient arm I I, carrying a latch I2, isprovided and secured to the head 2 by a screw I4. The part I5 of thegroove I0 is downwardly inclined to allow a vertical movement of the armII, as may be seen in Fig. 1.

To attach a setting to the band, one screws the bolt 8, which is securedto the setting by riveting or in any other suitable manner, into theaperture 4 of the band until the setting is tightly .screwed to theband. Thereby the latch I2 engages one of the notches 9, and since theside I6 of the latch I2 projects perpendicularly from the arm II, itsecures the screw connection between setting and band so that thesetting cannot become loose and cannot unscrew itself from the band.

To detach the setting from a band, one presses the arm II downwardlyasdeep as possible into the part I5 of the groove I0, whereby the latch I2disengages the notches 9, and then the setting can be unscrewed from theband.

According to the modification of the invention shown in Figs. 5 and 6,the ring band I is also provided with a head 2, having a flat surface 3,with an inwardly threaded aperture 4 in its center, and a threaded pin 8is secured to the bottom of the setting 5. In this case, however, thebottom of the setting 5 is not provided with notches, and instead of aresilient arm and a latch, a set screw I8 and a lock nut I9 are used.

The set screw I8 can be screwed into a threaded hole at one side of thehead 2 so that it presses radially upon the pin 8, thus preventing thepin 8 from unscrewing. As a second securing means, a lock nut I9 may bescrewed on the lower part of the pin 8, and the lower part of theaperture 4 is countersunk or provided with a recess which allows thetightening of the lock nut I9 by means of a short elbowed box spannernot shown.

The ring band and the setting can also be made without lock nut I9,without set screw I8, and without a resilient arm carrying a latch I2,so that the setting is simply secured to the band by screwing the bolt 8into the band.

Further modifications will be apparent to those skilled in the art andit is desired, therefore, that my invention be limited only by the priorart as determined by the scope of the appended claim.

Having thus described my invention, what I claim and desire to secure byLetters Patent in the United States is:

In a finger ring, the combination of a ring band having a fiat head withan internally threaded aperture in its center, with a setting having afiat bottom to which a threaded pin is secured and which has notchesaround said pin, and a latch carried by a resilient arm which is securedto said ring band, said latch being adapt- 5 ed to engage said notchesat the bottom of the setting, substantially as described.

MITCHEL FITZER.
